Susan Powter — Stop the Insanity! 1990s Sweatshirt

Susan Powter. 1993. Bleached buzz cut, bright red lipstick, and a woman screaming at America to STOP THE INSANITY! Long before wellness influencers took over Instagram, there was one very loud blonde lady on late-night television who absolutely refused to shut up.

If you were awake at 2 AM in the early 1990s, chances are you encountered Susan Powter, the Australian-born fitness guru who became one of the most recognizable faces of the infomercial era.

And once you saw her, you certainly didn't forget her.

With her platinum-blonde buzz cut, enormous personality, and a speaking voice that seemed permanently set to maximum volume, Powter was unlike anyone else selling exercise programs on television.

Forget the leg warmers, perky aerobics instructors, and cheerful encouragement of the Jane Fonda generation.

Susan was pissed off.

After struggling with her weight following a difficult divorce, Powter developed her own approach to fitness and nutrition, opening a wellness center in Dallas, Texas, before taking her message to television.

Her philosophy was fairly simple: stop starving yourself, stop wasting money on ridiculous diets, eat properly, breathe, and get moving.

But it wasn't necessarily what she was saying that made her famous.

It was HOW she said it.

In 1993, her Stop the Insanity! infomercial became a late-night television phenomenon. There she was, pacing around a stage, waving her arms, yelling at an audience of women, and attacking the multibillion-dollar diet industry with the intensity of someone who had just discovered her husband sleeping with the babysitter.

And America loved it.

Her accompanying fitness program, complete with audiotapes, exercise videos, nutritional guides, and a body-fat measuring device, sold by the hundreds of thousands. Her 1993 book, Stop the Insanity!, became a bestseller, and Powter quickly transformed herself into a multimillion-dollar fitness empire.

By 1994, she had her own nationally syndicated television program, The Susan Powter Show, and was appearing everywhere from magazine covers to television talk shows.

She even became the subject of a Saturday Night Live parody, which, in the 1990s, was practically a certificate of cultural importance.

And then, almost as quickly as she'd appeared, Susan seemed to vanish.

Behind the scenes, business disputes, lawsuits, and financial problems gradually dismantled the empire she'd created. After earning millions during her peak years, Powter eventually found herself struggling financially, a remarkable reversal for a woman who had once been one of television's most successful pitchwomen.

Her story received renewed attention decades later, including a documentary exploring the extraordinary rise and fall of the woman who had once been impossible to escape on American television.

But for anyone who remembers the glorious insanity of 1990s infomercials, Susan Powter remains an absolute icon.
